What this topic covers

Informed consent sits inside the Management of Care category of the NCLEX-RN. Our bank holds 49 verified items tagged to it, and the 4 below are a fixed sample so the page stays the same every time you open it. Each one shows the reasoning, not just the letter.

The topic tag comes from our own items rather than from a published syllabus, so treat it as a map of what we cover. For the official category breakdown see the NCLEX-RN page.

Informed consent sample questions

Question 1

A 68-year-old client is scheduled for a colonoscopy under moderate sedation. The client asks the nurse, 'What exactly will they do during the procedure?' Which nursing action is most appropriate regarding informed consent?

  1. A Provide a brief description of the procedure and document that the client understood the explanation
  2. B Explain the procedure in detail, including risks, benefits, and alternatives, then have the client sign the consent form
  3. C Notify the health care provider that the client has questions about the procedure before the consent is signed
  4. D Ask the client to sign the consent form now, and tell them the provider will answer questions later
Show the answer and explanation

Correct answer: C

The client's question shows that informed consent is not yet complete. The provider performing the procedure must explain what will be done, including risks, benefits, and alternatives, so the nurse should notify the provider before the consent form is signed.

Why the other options are wrong:
A: A brief description from the nurse does not meet the provider's legal duty to inform the client.
B: Explaining risks, benefits, and alternatives and obtaining consent are the provider's responsibilities, not the nurse's.
D: The client's questions must be answered before signing; consent signed without understanding is not valid.

Question 2

A 30-year-old client who speaks limited English is scheduled for an elective cholecystectomy. The surgeon speaks English only. Which action by the nurse best ensures that informed consent is valid?

  1. A Ask a bilingual family member to interpret the risks and benefits of the surgery for the client.
  2. B Use a hospital-approved medical interpreter to translate the surgeon's explanation to the client.
  3. C Have the client sign the consent form after the surgeon explains the procedure using simple words.
  4. D Provide the client with a translated consent form to read and sign without verbal explanation.
Show the answer and explanation

Correct answer: B

A hospital-approved medical interpreter provides accurate, unbiased translation of the surgeon's explanation of risks, benefits, and alternatives and lets the client ask questions. This is required for valid informed consent when a client has limited English proficiency.

Why the other options are wrong:
A: Family members may lack medical vocabulary, may filter information, and compromise privacy, so they should not interpret consent discussions.
C: Simpler English words do not overcome a language barrier, so the client may still not understand.
D: A translated form without a verbal explanation does not allow the client to ask questions or confirm understanding.

Question 3

A 50-year-old client is scheduled for an elective cardiac catheterization. The nurse enters the room to witness the client's signature on the consent form. The client states, "I don't really understand why I need this procedure." What should the nurse do first?

  1. A Have the client sign the consent form and then notify the provider of the client's concerns
  2. B Explain the purpose and risks of the procedure to the client and obtain the signature
  3. C Ask a family member to explain the procedure to the client before signing
  4. D Delay obtaining the signature and notify the provider to provide further explanation to the client
Show the answer and explanation

Correct answer: D

The client's statement shows that informed consent has not been achieved. Explaining the procedure, its purpose, and its risks is the provider's responsibility, so the nurse should hold off on the signature and notify the provider to clarify before the client signs.

Why the other options are wrong:
A: Witnessing the signature of a client who says they do not understand violates informed consent, even if the provider is told afterward.
B: Explaining the purpose and risks of the procedure is the provider's legal duty; the nurse's role is to witness the signature.
C: A family member cannot take the place of the provider in explaining the procedure, and the client's own understanding is what matters.

Question 4

A 45-year-old client is scheduled for a laparoscopic cholecystectomy. The surgeon has explained the procedure and risks, and the client has signed the consent form. The nurse is preparing the client for surgery. Which finding requires the nurse to withhold the procedure and notify the surgeon?

  1. A The client states, 'I think I am having the surgery on my stomach, not my gallbladder.'
  2. B The client's laboratory results show a hemoglobin level of 12.5 g/dL and a hematocrit of 38%.
  3. C The client's blood pressure is 148/92 mm Hg, which is higher than the preoperative baseline.
  4. D The client asks the nurse, 'Will I be awake during the surgery?' and appears anxious.
Show the answer and explanation

Correct answer: A

Informed consent requires that the client understands the procedure. Believing the surgery is on the stomach rather than the gallbladder shows the consent is not truly informed, so the nurse withholds the procedure and notifies the surgeon.

Why the other options are wrong:
B: A hemoglobin of 12.5 g/dL and hematocrit of 38% are within normal limits.
C: A mildly elevated blood pressure is common before surgery and should be reported, but it does not invalidate consent.
D: Asking about anesthesia and feeling anxious are common and can be addressed with teaching.
